Catch API bugs before they burn production

Apifighter is the visual, multi-user test flow runner built for QA engineers who need high-fidelity API validation.

Get on Microsoft Store

Free Desktop Beta. All data stays local on your device.

100% Offline & Local-First: Your API endpoints, private variables, tokens, and response logs never leave your machine. No cloud storage, no account registration requirements, no tracking.

Built for QA engineers
to help them find bugs sooner and sleep well

Stop checking isolated requests.
Run full test flow scenarios across multiple users and states automatically.

Build visual test flow from blocks

Define multi-step API journeys visually with a drag-and-drop composer.

Avoid test flows duplication

Define a step variant to the right of any step. The runner auto-expands all combinations.

Switch identity on each step

Assign steps to different user profiles. Test document sharing, permissions, and cross-account actions seamlessly in a single test flow.

Visual & Local Workflow

How apifighter Works

Define your requests and indenties, create test flows, run them to get a report.

1

Import OpenAPI

Provide your OpenAPI / Swagger specification JSON file or URL to seed your REST API request catalog instantly.

2

Setup Identities

Configure user profiles (e.g. Admin, Buyer, Guest) with credentials, auth headers, and variables.

3

Build Flows Visually

Chain requests vertically. Add horizontal variant requests to test multiple scenarios at once.

4

Run Locally

Execute scenarios directly from your desktop. No data is stored in any cloud. No tracking either.

5

Inspect Status Codes

See exactly which step failed and inspect the HTTP status code and response.

6

Get ready-to-copy report

Copy detailed execution reports ready to paste directly into JIRA issues — in Markdown or HTML formats.
